Abstract (en)
[origin: EP0278699A2] A method and an apparatus are provided for burning gaseous fuel when the composition of the fuel varies at times. Main injection ports and sub-injection ports are arranged so that the fuel injected through the sub-injection ports is ignited by the flame formed from the fuel injected through the main injection ports. Fuel passages (22,23) are provided for conducting the gaseous fuel separately to the two groups of injection ports. A control valve (24) adjusts the ratio of the fuel flow to the main injection ports to the fuel flow to the sub-injection ports. In operation the proportion of the fuel to be injected through the main injection ports is increased as the rate of burning of the gaseous fuel increases.
